Abstract

[PROBLEMS] To prevent metallic noise generated in the process in which the armor is in contact with each other when the bellows expands and contracts, and the appearance of the surface of the armor is impaired and wear powder is generated and the armor repeats the contact friction operation. A foldable bellows made of cloth with a plastic plate insert armor is provided. A resin plate made of a thermoplastic resin formed by applying heat to a cloth cover cloth 1 in which a woven cloth is coated with a thermoplastic resin to fold the fold cloth alternately to a predetermined folding width to form a valley and to cut into a predetermined dimension. 2 is inserted along the crease of the cloth cover cloth, and a metal thin film is placed in the vicinity of the back part or side part of the resin plate welded cloth bellows formed by welding with a heated hot plate or both peak parts. In a foldable bellows made of cloth with armor in which a plurality of strips (armor) 3 made of plate material are fixed or swingable, the strips (armor) 3 and the strips (armor) 3 Different materials (resin thin plate 4) are inserted and locked between them, and the direct contact between the strips (armor) 3 is indirect contact.

Description

The present invention mainly relates to a protective cover for machine tools and other industrial industrial machines.

The bellows shape loses its shape in the bellows used for the purpose of following the movement of a machine such as a machine tool to protect the drive linear guide, protect the ball screw or avoid danger to the human body, and improve the environment. In addition, a high-rigidity and lightweight bellows made of a resin plate welded cloth is used as a utility model No. 3047274 and a foldable bellows with armored cloth that has a long life even in a use environment of a large amount of cutting fluid and high-temperature cutting powder. Registered utility model No. 3056019 The applicant has devised.
However, in recent machine tools etc., not only the bellows original drive linear guide protection, ball screw protection or danger avoidance to the human body, environmental improvement, but also appearance aesthetics and noise reduction are required. There was a problem that the current product could not satisfy them.

In order to solve these problems, in the folding bellows made of armored cloth, when the bellows expand and contract, the armor contacts with each other and the friction between the surfaces of the armor deteriorates. It was necessary to develop a bellows equipped with a function to prevent metallic noise generated in the process of repetition.

The present invention has been intensively studied to solve such a problem, and relates to a folding bellows made of cloth with a resin plate insertion armor, and the contents thereof will be described below with reference to the drawings.
The armored cloth folding bellows devised by the inventor is composed of a cloth cover cloth 1, a resin plate 2, and a strip-shaped body (armor) 3. When the bellows are expanded and contracted, the strip-shaped bodies (armor) 3 are connected to each other. As a result of repeated contact operation, the surface of this strip (armor) 3 is polished by friction, and the texture and aesthetics of the initial strip (armor) 3 are lost. There was a problem of generating a rubbing sound due to powder.
Therefore, a different material (in the embodiment, resin thin plate 4) is inserted and locked between the strip (armor) 3 and the strip (armor) 3, and the direct contact between the strips (armor) 3 is indirect contact. This solves this problem.

In the in-house evaluation test, in order to avoid direct contact between the strips (armor) 3, different materials between the strips (armor) 3 and the strips (armor) 3 (in the embodiment, resin thin plate) As a result of inserting and locking 4) and extending and contracting, a clear effect was confirmed as compared with the state before installation. The direct contact between the strips (armor) 3 is avoided, the texture and aesthetics of the strips (armor) 3 are not impaired, the phenomenon of generation of wear powder can be prevented, and wear powder is generated. This is a very quiet state where no rubbing sound is generated, and the effect of the present invention was confirmed.

The cloth-foldable bellows with a resin plate insertion armor according to claim 1 is shown in FIG. Further, FIG. 2 shows a folding bellows made of cloth with armor that is a prototype of a cloth folding bellows with resin board insertion armor, and FIG. 1 shows a bellows made of resin board welding cloth.

Resin plate insertion armored cloth foldable bellows FIG. 3 shows that the resin thin plate 4 is inserted and locked between the strip body (armor) 3 and the strip body (armor) 3 of FIG. The shape of the resin thin plate 4 is the same as that of the strip-shaped body (armor) 3 or slightly larger than the outer periphery of the strip-shaped body (armor) 3, and the strip-shaped body (armor) 3 directly. The dimensions are such that they do not contact each other. The resin thin plate 4 avoids direct contact between the strips (armor) 3, prevents the texture and aesthetics of the strips (armor) 3 from being impaired, and prevents the phenomenon of generation of wear powder. As a result, no abrasion powder was generated, and a very quiet state with no rubbing noise was obtained.
